OEX ACX2811 12 Pin Flat Trailer Socket Dual Row 7-Pin 20A and 5-Pin 35A with Nickel Plated Brass Terminals
The OEX ACX2811 is a 12-pin flat trailer socket in a dual-row configuration, combining a 7-pin row (rated 20A) and a 5-pin row (rated 35A) in a single connector. The 7-pin section handles standard trailer lighting and braking circuits, while the 5-pin section accommodates higher-current auxiliary connections such as battery charging, 240V shore power switching or air conditioning control. Nickel plated brass pins secured with Phillips head screws. Plastic wire cap included. Supplied as a single unit. Covered by a one year warranty.
Product overview
The 12-pin flat connector extends the standard 7-pin format with an additional 5-pin auxiliary row, serving modern caravans with electrical systems that go beyond what the 7-pin flat can accommodate. Where a 7-pin flat carries standard lighting, braking and basic battery charging circuits, the 12-pin adds capacity for battery chargers drawing higher current, 240V AC switching, air conditioning control and other high-draw caravan services.
The 7-pin row is rated at 20A per circuit and the 5-pin row at 35A per circuit. Ensure circuits are matched to the correct row based on current requirements. The nickel plated brass pins are secured with Phillips head screws for straightforward terminal tightening and reliable long-term connections. The plastic wire cap protects wiring entries from moisture and debris. The ACX2811 is the socket (vehicle or tow bar side). A matching 12-pin flat plug is required for the trailer or caravan side of the connection.

Frequently asked questions
What is a 12-pin flat trailer connector used for? The 12-pin flat connector extends the standard 7-pin format with an additional 5-pin auxiliary row. The 7-pin row handles standard lighting and braking functions, while the 5-pin row carries higher-current circuits such as battery charging, 240V AC switching, air conditioning control and other caravan auxiliary loads.
What are the amp ratings for each row? The 7-pin row is rated at 20A per circuit and the 5-pin row is rated at 35A per circuit. Match circuits to the correct row based on current requirements.
What is the difference between a 7-pin flat and a 12-pin flat connector? A 7-pin flat handles standard trailer lighting, braking and battery charging circuits. A 12-pin flat adds a 5-pin auxiliary row for higher-current caravan services. Modern caravans with air conditioning, a 240V inlet or other high-draw systems typically require a 12-pin connection.
Is the matching plug included? No. The ACX2811 is the socket only. A matching 12-pin flat plug is required for the trailer or caravan side of the connection. Check the OEX trailer connector range for the correct counterpart.
Is this socket weatherproof? Weatherproofing is not specified for this SKU. Confirm the sealing specification with OEX if weatherproofing is a requirement for your installation.
